Abstract: An engine control device capable of accurately detecting the missing of crank pulses and the erroneous detection of the crank pulses due to generation of noise, wherein a tooth-less part on the outer periphery of a toothed crankshaft for feeding the crank pulses, the erroneous detection of the crank pulses is detected by using the instantaneous value of the rotational speed of the crankshaft calculated by using the crank pulses from the tooth-less part and the teeth across the tooth-less part, and since the instantaneous value of the rotational speed of the crankshaft calculated by using the crank pulses is suddenly decreased and then suddenly increased when the crank pulses are less detected erroneously, the number of the crank pulses less detected is detected by using the number of the crank pulses during that time and, since the instantaneous value of the rotational speed of the crankshaft is suddenly increased and then suddenly decreased when the number of the crank pulses is more detected erroneously, the number of the crank pulses more detected is detected by using the number of the crank pulses during that time.
